Just tried to pop a X-240 and fan kit into a PS2AC and I appear to be missing the transformer shroud. I sent off a plaintive note to my supplier but then looking more carefully at the installation drawing it would appear the shroud is designed for the larger PSAC. Is this correct?

If it is, then I humbly ask you to make that more clear in your documentation. If I have no other choice, then I intend to mount the fan over the box vent opening, pressurize the box and vent the hot air out the top through a (screened) 2" opening. I'm wondering if I should derate the transformer down fom the 6kVA (fan-assisted) rating if I don't use the fan shroud? I am using the X-240/fan combo to convert the 240VAC from my 6 kW generator to 120 for the the inverter chargers and my AC loads.

Yes, the fan fits there nicely. I've got it blowing in and will fabricate an aluminum baffle to force more air up towards the transformer. I punched out a bunch of knockouts out of the box- top and will cover with some screening. Then I'll do the dreaded "hand on the transformer" test and see how long I can keep it there at my 4.8kW design minimum (It's between the generator and the inverters/AC loads as a step-down transformer).

That was an old old thread...I would love to have had one of those IR guns. The hand was...well...all I had at hand at the time. For the record, the transformer has worked flawlessly all these years. I just bought a second one to run a 240 VAC well pump off the inverters.

Yup, since 2003 you should have a good idea of how many watts you can run through the X-240? ;-) I'm just curious as in the winter, the only continuous load on this step down circuit from the genset would be for battery charging and that is only 20 amps @ 120v, when active. Obviously, there are minor household loads too. Last winter season I had the AC current limit set at 29 AAC (3480w) and even with a 25a breaker, it never tripped. I don't have a fan on it but it is with the rest of the stuff in a crawl space which is chilly on the winter.

Just curious as 4.8kW seemed a bit of a stretch over margins of safety.
